摘要： The invention relates to a control device (1) for an electrical machine. The control device (1) comprises a housing (2) partially surrounding a housing interior (3). The housing (2) comprises a lower housing part (4) made of metal, preferably of aluminum, and with an upper housing part (5) made of plastic. A printed circuit board (6) is arranged in the housing interior (3) between the housing lower part (4) and the housing upper part (5), on whose upper side (7) facing the housing upper part (5) at least one electrical/electronic power transistor (8) for supplying the electrical machine with electrical energy is arranged, which generates waste heat during operation. According to the invention, a biasing element (10) is arranged between the at least one power transistor (8) and the upper housing part (5), which biases the power transistor (8) against the lower housing part (4) to form a thermal contact.

摘要： The invention relates to an inverter (1) for an electric motor (32). The inverter (1) comprises a capacitor plate (11) comprising several capacitors (12), several transistor plates (7) each comprising several transistors (8), a cooling plate (9), and a control board (16). The inverter (1) comprises a hollow cylindrical carrier (2) comprising a central axis (3). The control board (16), the capacitor plate (11), the respective transistor plates (7), and the cooling plate (9) are located axially one on top of the other. The cooling plate (9) axially closes the carrier (2), which receives the capacitor plate (11), the transistor plates (7), and the control board (16), and encases them in the circumferential direction to the outside. The capacitor plate (11), the respective transistor plates (7), and the control board (16) are electrically interconnected.
According to the invention, the carrier (2) supports the capacitor plate (11), the transistor plates (7), and the control board (16), and the inverter (1) forms a cohesive and assembly-ready assembly unit with the carrier (2), the capacitor plate (11), the transistor plates (7), the cooling plate (9) and the control board (16).
The invention also relates to an electric motor (32) comprising the inverter (1).-
